WATER-DISPENSING DEVICE.

Specification of Letters Patent.

Application filed February 23. 1915. Serial No. 9,923.

To all whom it may concern:

Be it known that we, CHARLES DOERING, Jr., of Oak Park, Cook county. Illinois. and MAX A. DOERING, of Chicago, Cook county, Illinois, both citizens of the United States, have invented certain new and use ful Improvements in ater-Dispensing De vices; and we do hereby declare the follow- -ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide improvements in liquid dispensing devices and particularly to that class of de vices in which liquid is fed directly from an inverted bottle or similar reservoir containing the same which is adapted to be mounted upon and removed from the cooler or other dispensing device for transportation to and from a source of supply. a

The particular object of the invention is to provide means for connecting the inverted bottle with another receptacle for causing the liquid from thebottle to flow into said receptacle, so constructed and arranged as to v prevent any liquid flowing from the bottle coming in contact with exterior surfaces of the latter which are usually manually engaged in and prior to disposing the bottle l in inverted position upon the receptacle or dispensing device.

Another object of the invention is to provide means in the mouth of the bottle or 5 similar reservoir for maintaining the same sealed until communication with another receptacle hasbeen established, and in which the means connecting the same with another receptacle effect an opening of the bottle 4 sealing means without permitting leakage.

Another object ofthe invention is to provide bottle sealing means adapted to automatically close upon removal of the bottle rom the means connecting the same with 4 another receptacle or dispensing device.

In the accompanyingdrawings illustrating a suitable embodiment of the invention:

Figure -l is a view in vertical longitudinal section of the neck portion includmg a part of the body portion of a bottle of the character in which drinking water is usually distributed, showing the same mounted in inverted position upon a support equipped with means for-connecting the interior of the bottle with a receptacle 'for the contents thereof, sa1d last-named parts be ing fragmentarily illustrated.

'vided between its ends Fig. 2 is an inner end view of a stopper for normally maintaining the bottle sealed.

Fig. 3 is a view similar to Fig. 1 showing a modified form of construction of stopper or sealing device for the bottle.

Fig. 4c is an inner end elevation of the stopper or sealing device shown in Fig.

Referring now to said drawings A indicates the top wall or cover of the housing for an ordinary water cooler from which water is adapted to be dispensed from a faucet, and which is provided with an opening 3 through which the contracted end portion C of a cup D projects into the housing. The said contracted portion C of said cup D is cylindrical and is adapted to telescopically receive the upper end portion E of a receptacle adapted to receive liquid from the inverted bottle F, the latter being supported upon the rim of the cup D in a Well-known manner. The upper ortop wall G of the said portion E of said receptacle is provided with a central upwardly extending stem or nozzle H provided in its upper end with openings I, and which is adapted to pass through the stopper J in the mouth of the bottle F and receive liquid from the latter, which passes through the same into the said receptacle.

The stopper J is preferably composed of rubber or a similar suitable material and is provided with an annular flange K adapted to restupon the rim of the bottle to limit the projection of the. stopper J into said bottle and it is further provided with a tapered central opening L adapted to receive the said nozzle H, the latter being prowith an annularly enlarged or bulged portion M for effecting a fiuid-tight joint around'said nozzle, between the ends of said stopper J. Upon the with the body of said stopper and being formed by cutting an incision laterally of the latter parallel with its inner end and extending almost through the same whereby said valve N becomes flexibly connected with the body of the stopper J and normally maintains the inner end of the central opening L therein sealed.

The length of the nozzle H-is such that when the bottle is. disposed in the position shown in Fig. 1-, the said'nozzle will pass entirely through the said stopper J 100 inner end of said stopper J a valve N is mounted, the latter being preferably integral verted without spilling any of the stopper mally maintains 'liquid cannot find its -handled by delivery 0 mounting of the same 1n inverted positionshown in Figs.

and will contact at its inner end with the valve N and open the latter whereupon, liquid from the bottle will pass into the openings I and thence into the said receptacle E. Thus the bottle may be readily inthe contents thereof during inversion and prior to eitecting communication between the interior of same and said receptacle J- The construction may be variously modified and a suitable modification thereof is illustrated in Figs.

O is provided between its ends and adjacent its inner end with a hollow chamber I, the inner wall of said stopper being conical and being provided with an incision Q intersecting the apex of the cone,

and which is adapted to be openedby the projection of the nozzle, H therethrough. Between the chamber P and the outer end of the stopper 0 is a passage of normally smaller diameter than the nozzle H so that the latter in passing through said stopper will expand said opening am at the same time effect a fluid-tight joint between the stopper and said nozzle. The annular bulge M of the nozzle is adapted to seat around the I outer end of said contracted portion to further insure a fluid-tight joint at this point.

The incision Q is normally maintaine closed by theresi iency of the material 0 which the stopper Q is composed and northe bottle sealed, and will automatically seal the same upon withdraw ing the nozzle H from said stopper 0 In the event of any leakage past the nozzle and into the chamber R above the upper wall G of the receptacle E such y into the latter, but is preferably drained from said space by a small pipe S passing through an opening in said top wall G and through an opening in;.,the circumferential wall of said receptacle E. p

It will be obvious that our invention provides a throughly ing the interior of a bottle or similar removable reservoir w-ith thedispensing recgptacle of a cooler or other device inasmuch as the liquid flowing from the bottle or reservoir.

cannot come anyof the ex in contact with terior surfaces of the latter which have been teamsters or other persons in f the bottle and in effecting the upon the cooler. The invention also permits a partially empty bottle still containing liquid being removed and 2 without liquid to be spilled during such causing any an opening ends for compressing from the b at pressible closure sanitary mode of connectfrom the position and a removable reservow,

to project into the reservoir, and a va ve stopper for the reservoir normally maintaining the latter sealed and adapted to receive said nozzle, the nozzle automatically opening the valve of said stopper, the stopper provided with a circumferential enlargement belowits upper end adapted to maintain a fluid-tight joint around the exterior of said nozzle for preventing leakage from saidreservoir as said valve is opened.

2. In a liquid dispensing'apparatus of the kind specified, the combination with a receiving receptacle and a removable reservoir for liquid, of automatically coacting means for effecting connection between the inte riors of said parts, comprising a yielding stopper for the removable reservoir having an opening inner end thereof for controlling said opening for preventing flow of liquid from the reservoir, and a nozzle rigid with a part of the receiving receptacle and provided with for admitting liquid to the latter, said nozzle being adapted to pass through the opening in said stopper and open the valve controlling the same to permit passage of liquid into said nozzle, and a circumferential enlargement on the nozzle between its the body of the nozzle below its inner end to efiect a fluid tight joint between the nozzle and the stopper.

3. The improvements herein described comprising a closed liquid reservoir, a comtherefor having a passage adapted to afiord communication with the interior of the reservoir, an integral valve located at and normally closing the inner end of said passage, a liquid receiving receptacle an upstanding rigid nozzle thereon adapted when the reservoir is superposed upon the receptacle to enter said passage open flow from the reservo r into the receptacle, said nozzle provided with a rounded enlargement removed from its free end adapted to compress the walls ofthe closure below the inner end thereof to form a fluid tight joint therebetween.

In testimony whereof we names in presence of two nesses.
